If Kim wanted to create a function that modeled an exponential function with base of 7 and what exponents were needed to reach specific values, how would she set up her function? f(x) = x7 f(x) = 7x f(x) = log7x f(x) = logx7

Your answer is f(x) = log₇(x) hope this helps

Answer:


f(x) = x^7

Explanation:

Given that Kim wanted to create a function that modeled an exponential function with base of 7

So the appropriate function would be


y=7^x

which is exponential with base 7, passing through (0,1) and have range as only positive values of y.

y=0 will be an asymptote for this graph.

Other functions are wrong because


f(x) = x^7 is a polynomial funciton and not exponential

Similarly
log_(7) x is a logrithmic funciton and the next also

Hence right answer is option 2.
